Kill PPP, GRUB, Floppy Boot

["Jim Michael" <jim.michael@toadmail.com>]

1.  How can I hang up a ppp connection initiated with "ppp -auto" or "ppp
-ddial"?

2.  I would like to use GRUB for two multi boot machines but I haven't been
able to get to the download page for sometime alpha.gnu.org:/gnu/grub.  Is it
available anywhere else on the web?  (I sent email messages to the people at
GNU but received no reply).

3.  Is it possible to boot OpenBSD on a second hard disk from a floppy?

Thanks.
